fast-style-transfer webcam script

This is a fork of fast-style-transfer which has an additional script, run_webcam.py to apply style models live to a webcam stream. Go to the README of the original page for instructions on how to train your own models, apply them to images and movies, and all the original functionality of that repository.

Installation

• CUDA + CuDNN
• TensorFlow GPU-enabled
• OpenCV (this is tested on cv 2.4, not most recent, but presumably both work)

Setting up models

Pre-trained models for Picasso, Hokusai, Kandinsky, Liechtenstein, Wu Guanzhong, Ibrahim el-Salahi, and Google Maps.

At the top of the file run_webcam.py, there are paths to model files and style images in the variable list models. They are not included in the repo because of space. If you'd like to use the pre-trained models referred to up there, these models may be downloaded from this shared folder. To train your own, refer to the original documentation.

Usage

python run_webcam.py --width 360 --disp_width 800 --disp_source 1 --horizontal 1

There are three arguments:

• width refers to the width in pixels of the image being restyled (the webcam will be scaled down or up to this size).
• disp_width is the width in pixels of the image to be shown on the screen. The restyled image is resized to this after being generated. Having disp_width > width lets you run the model more quickly but generate a bigger image of lesser quality.
• disp_source is whether or not to display the content image (webcam) and corresponding style image alongside the output image (1 by default, i.e. True)
• horizontal is whether to concatenate content/style with output image horizontally (1, which is default) or vertically (0). Only relevant if disp_source=1

You can toggle between the different models by hitting the 'a' and 's' keys on your keyboard.

Example

Requirements

You will need the following to run the above:

• TensorFlow 0.11.0
• Python 2.7.9, Pillow 3.4.2, scipy 0.18.1, numpy 1.11.2
• If you want to train (and don't want to wait for 4 months):
  • A decent GPU
  • All the required NVIDIA software to run TF on a GPU (cuda, etc)
• ffmpeg 3.1.3 if you want to stylize video
